Life Change Church Seattle - New System

Life Change Church Seattle


Associate Pastor Art Nelson would like the room to sound like a recording studio control room. His comment on the existing system: It has a mushy bottom end, with it sounding very different depending on where you sit in the seating area.

Project: Upgrade Sound, Video, Acoustic Treatment, and Lighting

Design Parameters:

  • Acoustics - room to have a sound signature similar to a recording studio control room. Adding bass traps, panels and diffusion. (see drawings below)
  • Sound - Total new system, converting to digital, centered around a Midas M-32 mixer with 48 channels to platform. Speaker choice is the ISP HDL 3112 3-way line array with the ISP XMAX 212 Sub Woofers (all active) XTA processing and installed in a LCR configuration.(see SketchUp drawing below)
  • Lighting - All new lights to be LED including house lighting. Some par fixtures and a lot of robotics.

Existing System:
  • Acoustics - None, no acoustic treatments of any kind in the existing room.
  • Sound - 2 x EAW Passive MK Series Club Speakers, Mackie SWA 1801 Active Sub Woofers, QSC amps (mains & monitors), Mackie SR 32-4 VLZ console, 4 stage pockets with 8 x XLR & 4 x 1/4” connectors.
  • Lighting - House light consist of residential hanging globe fixtures and track light for stage area.
  • Video - projection system on to a painted-on-wall screen in 4:3 format approx. 100” diagonal
  • Room size is 40’ x 40’, so this is a small room and their is a lot of energy put into the room from this system. The speakers are mounted in center cluster configuration, running mono. No processing of any kind, and amplifiers are located at the sound booth.

New Active 6" Line Array System

I recently visited the my distributor of light and sound products and Burt showed me a bunch of great new products.

Lights

A new robotic light in both spot and wash versions. Now these lights are going to take the market in a whole new direction. They are about the size of a big coffee can with a price point (under $1K retail) that will make it great for Houses of Worship, DJ, Club, and Touring applications (believe me they are bright enough). The great thing about these LED lights is the capability to have 32 fixtures on one 20 amp circuit.

I will post picture as soon as they go on sale.

Speakers

The Omnisistem B3 R6/R12 Line Array will be available in an active version within the next 2 weeks. Great news for churches with up to 2000 people/seats. they can be configured as follows:
these arrays are extremely compact and with the addition of subs on the floor give you a 5 way system. more....

Drum Surround DIY Diagram

Here is the "Live Stage" version of the Studio Gobo design.

The panel is 1/2 the density of the Studio Gobo design. You should notice that the surround uses two panel sizes. One 48" panel and four 36" panels to make the surround.
There are a couple of other things to notice as well, wheels that help you move the panels around and the space it provides for cable management.

Again I must point out that the most important ingredient to this design is the use of "Quietrock".

Line Arrays for Small Churches

Here is a temporary install of a mini line array for a small church in Tacoma WA. It is a temporary install because they are putting in a truss system very shortly and the speakers are not in the optimum position right now.

Here is a render of the future truss system with the speakers hanging in future location & a picture of where they are right now:
